| 摘 要： | 我国已知的铬铁矿床均属于中小型豆荚状铬铁矿床,分布区域不均衡,开发利用条件差。豆荚状铬铁矿床包括高铬型和高铝型,两种矿床的形成环境和机制各不相同。弧后弧前盆地、岛弧、大洋中脊、转换断层均可能是豆荚状铬铁矿形成的理想构造环境,越来越多的学者认为豆荚状铬铁矿为深部地幔成因。铬铁矿是我国急缺的战略矿产,需要加大重要铬铁矿带隐伏矿体的找矿力度。

| Abstract: | Chromite deposits in China are generally medium-small sized podiform ones and unevenly distributed with poor exploratioin and utilization condition. The podiform chromote deposits are composed of both high Cr and High Al ores with different ore-forming mechanism. Backarc and forearc basin, island arc and middle ocean ridge rige and transform fault are possibly favorable settings for podiform chromite formation. More and More scholars consider that podiform chromite is formed in deep mantle. Chromite is a strategic mineral resource and is in shortage in China and almost entirely imported. Therefore prospecting of blind chromite deposits in the known chromite ore-forming belts should be strengthened. |
